Harvest Gold Receives Rosebud Mine 2008 Enzyme Leach Results

Harvest Gold Corporation (HVG – TSX.V) October 22, 2008 (the “Company”) has received results for its Rosebud mine project enzyme leach soil survey. A total of 340 new samples were collected in the summer of 2008. The enzyme leach soil geochemical response has provided a layer of geochemical anomalies that coincide with geological mapping, airborne and ground geophysical surveys. Highlights include:

  • The enzyme leach analytical method is effective at the Rosebud Mine. The data provide compelling supporting evidence of subsurface mineralization through high-contrast gold responses above the concealed, previously-mined zones

  • A high-priority target, adjacent to the “chimney”, is indicated by enzyme leach gold responses. Over the underground workings, gold responses are highest above the chimney and immediately to the northwest where geology is favorable and drilling is sparse.  An historic crosscut drift in the chimney intersected 120 feet grading 1.3 oz Au/t (36.6 metres @ 44.6 grams/tonne).  The chimney was mined over a vertical extent of 220 feet (67 metres) and accounted for about 70% of the South Zone gold ounces.

  • Targets that are peripheral to the mine are enhanced and refined by enzyme leach gold responses, particularly in the Valley, Northeast, and Southern Extension target areas.  Multi-sample gold responses, accompanied by silver and other pathfinder elements, are also present above the Northeast and Valley targets, which are along strike to the northeast and southwest of the mine, respectively. Geophysical anomalies accompany the Northeast and Valley target enzyme leach signatures.  In the Valley target area, a north-trending induced polarization chargeability high coincides with the north-trending enzyme leach gold response, where limited drilling has intersected low-grade mineralization. 

  • Structural intersections between west-northwest, northeast and north-northwest fault zones faults and fault intersections are clearly identified, including those controlling mineralization in the previously-mined South, North, and East Zones.  In addition to forming gold anomalies directly above mineralized zones, these data define concealed structural features, thereby significantly increasing our understanding of the geologic framework at Rosebud.

A well-developed, zoned enzyme leach halo, is enriched in multiple elements and, is centered immediately to the northeast of the mine along strike of the Rosebud shear.  The East and North Zones are encompassed by the southwest portion of the enzyme leach halo whereas the South Zone is peripheral to it extending away from the central low in a radial fashion.  The Northeast target occupies a very similar position to the mine, but on the opposite margin of the halo.  The origin of this prominent halo is unknown, but it may represent a deep buried intrusion, volcanic center, and/or the center of a hydrothermal system that has produced gold mineralization along its periphery.


Enzyme leach analysis of B-horizon soils reveals element patterns (halos and apical anomalies) related to buried mineral deposits. The patterns formed by enzyme leach analysis of soils at Rosebud clearly indicate the presence of known subsurface gold mineralization.  Enzyme leach gold responses are anomalous in nearly every sample above the Rosebud mine whereas at least half of the soil samples analyzed by conventional soil geochemistry analysis are not anomalous in gold directly above the underground workings.  The gold anomalies shown by conventional analysis are also significantly dispersed by downslope mechanical transport of gold, while the enzyme leach gold anomalies are not.  Furthermore, targets such as the Valley, Northwest Corridor, and Northeast are indicated by similar enzyme leach gold responses, whereas the conventional gold patterns are discontinuous and weak or completely absent above these targets.


Samples were analyzed for Au, Ag, and 64 elements including base metals, trace elements, halides and rare earth elements by Skyline Assayers and Laboratories of Tucson, Arizona subsequent to enzyme leach extraction with an ICPMS finish.  Replicate samples show good data reproducibility.

Harvest Gold Corporation is a mineral exploration company working in Nevada, USA and Manitoba, Canada. In Nevada, the Company is exploring the 100% optioned Rosebud Mine property, located 5 miles to the South of the Hycroft Mine: a generative gold property at Garcia Flats in the South Carlin Trend: and, an advanced property with a gold-silver resource at the Longstreet Mine, in Northern Nye County. In Manitoba, Harvest is exploring three groups of claims in the Rice Lake Gold Belt of south eastern Manitoba and at Assean Lake, Manitoba.
